Pull textures from disk for editor listview thumbnails without importing? (Python/Blueprints)

I’ve been trying to find a way to do this, but haven’t had any luck so far. Essentially, I want to create a way to import static mesh assets from disk. If they have a thumbnail in the same folder, it finds the thumbnail and displays it in the editor utility widget with the name in a tile list entry. Is this possible? Everything I’m seeing seems to need you to import textures first, but because of the transient nature of this use that is out of the question generally.

Bump, anyone have any ideas? Or is it just not possible?
